BrainView and the scene controllers store all renderable surfaces in a single QMap<QString, std::shared_ptr<BrainSurface>>. The keys in this namespace are the canonical identifiers used by every controller to look up, replace or remove a surface without race conditions caused by typo'd magic strings.

Keys cover the two cortical hemispheres (lh / rh on each of pial, white, inflated, smoothwm), the three BEM compartments (brain, inner-skull, outer-skull, scalp), MEG helmet / iso-contour surfaces, and a few diagnostic primitives (origin marker, orientation gizmo).
